Corvette rally wheels question.

Ok after reading a ton of info here on wheel combos, JUST to be sure, the factory Corvette 8 x 15 wheels have a 4 inch back spacing and are hub centric. Are there any clearance issues using these on the back of a 67 Camaro with 255 60 BF Goodrich T/A"s ? And as these were disc brake equipped cars these wheels came on are the still hub centric on a drum brake rear end on a 67 Camaro? I have Wheel Vintique rallys all around now but I have a vibration at high speed I cant find and was thinking of putting hub centric original GM rallys on the car. I have 2 15 x 6 rallys from a Camaro / monte carlo I plan to use up front and was thinking of getting 2 15 x 8 vette rims for the back.
thanks

Re: Corvette rally wheels question.

I run the 15x8" AZ code Corvette rallies on the rear with 235/60-15 tires and drum brakes. Are they hub centric on the rear? I guess so, but use stock acorn-style steel lug nuts and you should have no problems at all and 255/60-15 is a common rear tire size also.

Not hub centric and never were. Not a big deal.

Re: Corvette rally wheels question.

Pretty sure the AZ coded Corvette wheels were hub concentric when I ran them with 245x60x15 tires.

Re: Corvette rally wheels question.

The hub centric issue is debatable.

Of course, non hub centric wheels need to be balanced with a lug centric type of machine.

Hub centric conversion rings are available, but I've heard the stamped hole in non HC wheels isn't always true or dead center, so the rings may actually be worse than relying on the lug nuts for centering. ??

https://www.camaros.net/forums/showth...+centric+rings

I'm pretty sure all GM wheels from the 60's -70's are hub centric. 15 x 8 AZ code vette wheels have 4" backspace. With a 255/ 60 tire, I think they'll be rubbing the wheel openings if the suspension allows the tire to travel that far.

Just my thoughts....

Re: Corvette rally wheels question.

I run 245x60 and 225x60 on my Vette wheels with no issues and they look great without being too big and have rubbing issues on my 69 RSSS Vert.

So they do not rub in your 69?

Re: Corvette rally wheels question.

I have had 15x8" rally wheel with 4" BS and 245/60-15 tires. They did rub the fender lip when the suspension was compressed. No problem with rubbing if no passengers in the rear seat. I am now using 17x8" rims with 4.5" BS and 245/45-17 tires without problems. Stock mono leafs.
A 245/60-15 tire on a 8" wide rim has a section width of 260 mm. A 245/45-17 tire on a 8" wide rim has section width of 245 mm. Measured by myself on my own tires.

Re: Corvette rally wheels question.

Larry,

I have 15 x 8 AZ coded 4” backspace Corvette Rally wheels and 255/60-15 BF Goodrich Radial TAs on my 67. Generally I have no rubbing. But if I let my old school air shocks get low and have someone in the back seat, if I hit a large hole or dip in the road I will rub the chrome trim on the wheel well. I’m still running drum brakes on the rear.

As far as hub centered, my understanding is all the Rally style wheels were hub centered, but I have limited knowledge on that topic. If you changed to aftermarket disc brakes I’m not sure if they’ll still center on the hub.

Re: Corvette rally wheels question.

My experience is 255's on Corvette rallys will rub (on the rear) unless you bend or trim the fender lip.

If you want rallys, go to summit and get the 4.5" backspace wheels for $78

Your 4" backspace wheels might work on the front, but 4.5" backspace is better

That's what I have now. I have a vibration I am trying to find and was going to try factory wheels as I have read multiple posts about the Wheel Vintiques causing vibrations.

Re: Corvette rally wheels question.

Think about it. A stamped out circle in the middle of a wheel going over a hub with a wide open tolerance on it. Hub centric wheels have a much tighter tolerance hub to wheel mounting hole and use flat backed lug nuts. All that hub is doing is help you get the wheel on the axle, tightening your lug nuts with the angle shoulders are what centers the wheels. I have talked to GM engineers about this as well as two different buddies who manage tire shops. Not hub centric. You know all those TT-IIs all the rage on first gen Camaros? Not hub centric. NO aftermarket wheel is hub centric.
